SPECIFICATION forming part of Letters Patent No. 399,667, dated March 19, 1889.

Application filed September 1, 1888. Serial No. 284,320. (No model.)

To ztZZ whom it nuty concern.-

Be it known that I, XVILLIAM F. HYATT, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Safety-Pins, of which the following is a specification.

The object of my improvement is to facilitate the insertion of the pointed limb of the pin into the shield and to retain the same securely in the shield after insertion.

I will describe a safety-pin embodying my improvement in detail, and then point outthe various novel features in the claims.

In the accompanying drawings, Figure l is a side view of a pin embodying my improvement, the pointed limb of the pin being in- Fig. 2 is a similar view but representing the pointed limb of the pin in the act of passing into the shield. Fig. 3 is a transverse section taken as indicated by the dotted line a: 00, Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

A designates the pin. It is made of a piece of wire bent at about the middle of its length into a coil, a, to form a spring, and having one of the two limbs a. a which extend from the coil, pointed.

B designates the shield. This shield is shown as made of sheet metal, with an opening in each side. The unpointed limb to of the pin is rigidlysecuii'ed in any suitable manner within the shield at one side of the latter. It may be secured by soldering, or it may be secured by pinching the shield upon it. It may be secured both .by pinching and soldering the shield. The opposite side of the shield is'shown as made wider than the pin is thick. This side of the shield is to receive the pointed limb of the pin. The inner edges, 1), of this side of the shield are shown as rounded or curved downwardly, inwardly, and upwardly, forming the curved extension near the closed end of the shield, and as extending almost over to the edges b of that side of the shield which is secured to the unpointed limb of the pin.

It is advantageous to round or incline the edges of that side of the shield which re side of the shield, because when they are so rounded or inclined the pointed limb of the pin can pass through a narrower opening than otherwise would be possible, owing to the fact that the rounding or inclining of the edges allows for the angle which the pointed limb of the pin assumes when bent to pass into the opening, and also, should the end of the pin become slightly bent, as often happens, the inner curve would allow the point to pass into the shield. It will be seen that the shield has a very narrow opening, through which the pointed limb of the pin may pass, and that the two edges Z) Z) are substantially parallel and stand at an angle to the length of the pointed limb when in its normal position. In the present example of my improve ment there is such an opening at each side of the shield; but this is not essential to the underlying principle of my invention.

It will also be observed that this narrow opening is close to that part of the shield which embraces the unpointed limb. hen, therefore, the pointed limb of the pin has been inserted in the shield, it cannot be disengaged from the shield, except by imparting to it a considerable movement. This renders the pin more secure.

The extension of the side edges of that side of the shield which receives the pointed limb laterally beyond the opposite edges of that side of the shield which is secured to the unpointed limb of the pin facilitates the introduction of the pointed limb of the pin into the shield.

By my improvement I produce a safety-pin the pointed limb of which may be very easily inserted into the shield, and will be very securely retained there after insertion.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. A safety-pin having a shield provided with a narrow opening and made Wider at that side which receives the pointed limb of the pin than that at the opposite side, which is rigidly secured to the unpointed limb, the inner edge of the wide side of the shield being curved downwardly, inwardly, and upwardly, substantially as specified.

2. A safety-pin having a shield rigidly secured to a limb of the pin, and havingawide retaining portion for the pointed limb of the pin, the edge of said wide portion adjacent to the narrow opening curved downwardly, in- Wardly, and upwardly, forming the curved extension, and the said edge extended laterally, substantially as specified.

3. A safety-pin having a shield provided with a narrow opening having its edges substantially parallel and standing at an angle to the length of the pin, the said shield being IO wider at that side which receives the pointed limb of the pin than at the opposite side, which is secured to the unpointed limb of the pin, substantially as specified.
